6 Claims.

This invention relates to improvements in vaporizing devices and isparticularly concerned With devices adapted to vaporize liquid fuel forinternal combustion engines, oil burners or the like.

It is an object of the invention to provide a device capable ofconverting liquid fuel into iinely divided vapor readily capable ofcombustion whereby utmost energy may be obtained l0, from such fuel.

A further object of the invention is to provide a device which isadapted to vaporize relatively heavy or high boiling motor uids, such askerosene and fuel oil, without necessity of employing i5 heat to assistor effect such vaporization.

A further object of the invention is to provide a device which, whenassociated with the suction side of a blower, an intake manifold, or thelike, is readily responsive to the suction therefrom v and will feedthereto in predetermined volume liquid fuel inA a finely dividedvaporous condition.

Still another object is to provide a vaporizing device having a novelarrangement of air ducts through which air may be drawn into thevaporizing chamber and into the liquid chamber preferably beneath thelevel of the liquid therein whereby to positively force the liquid/intothe vaporizing chamber and whereby to regulate the character or degreeof its vaporization.

Another object is to provide a vaporizing devicetional view of'avaporizing device embodying the principles of the herein invention.

Fig. 2 is a fragmentary section taken along line 2--2 of Fig. landlooking in the direction of the arrows.

Fig. 3 is a sectional view taken along line 3'-` 3 of FlgLl and lookingin the directionof the arrows.

Figf4 is a sideelevatinal view of thedevicev illustrated in Fig.'1lshown inas'sociation with the intake manifold 'of an internal*combustionv engine; and

Fig; 5 is afsi'de elevationalview ofA thedevice of Fig. 1` shownliriasrsoci'ation with thev suction side of yablo'werv as for an'oil`burning furnace or the like.

Referring more particularly to the drawings wherein like numerals referto like parts, a housing indicated generally at A includes at oppositeends thereof an elongated vaporizing compartment I8 and a liquidcompartment I2, Packed in 5 vaporizing compartment I0 and extendingsubstantially throughout the length thereof is a mass of steel wool orother equivalent material which is capable of dispersing the liquid intoan extremely finely divided vaporous condition during 1 its passagetherethrough. T he mass of steel wool I4 or other material havingequivalent characf teristics under the conditions herein also operatesas a ltering medium for the liquid fuel. Shoulders I6 or other suitablemeans may be provided inten'or-ly of the vaporizing chamber III tosupport at opposite ends thereof screens I8, which in turn serve tosupport and compact therebetween the mass of dispersing and filteringmaterial I4. 20

As clearly shown in Fig. 1, liquid chamber I2 is positioned at thebottom of cylindrical housing A and directly beneath and in opencommunication with the vaporizing chamber I8'. Liquid is introduced tothe chamber I2 through inlet connec- 25 tion 20 and the liquid thereinmay be maintained at a predetermined level by means of a novel floatvalve arrangement including the disc oat member 22 which bears upon alever 24 which in turn pivotally supports and suspends a valve stem 3026 carrying a valve 28 which is adapted to cooperate with a seat 30formed in the liquid feed line 20.

Disposed axially of the housing A and extending vaxially throughout thelength of the vapor- 36 izing chamber I0 and liquid chamber I2 is aninternal iiue indicated generally at 32 carrying at its lower end a yokemember 34 which receives the valve stem 38 of a safety or release valve38 normally urged ink seated position upon the end 40 -of thefiue 32 bymeans of a tension spring 40.

Safety valve 38 serves to readilyrelease pressure rresulting `from anybackfire or the like whereby chamber I2so`thatthe liquid chamber is dis=posed circumferentially of theilue makes possible the vnovel oat valvearrangement wherein 50, the ringlike iioat V22Imay be'fdisposedannularly f of theexterior wallof the ue 32 'and be guided thereby. Y Hi Disposed circumferentially ofthe vhousing Af at the end thereofforming the liquid compartment I2 and the lower vportion of thevaporizing compartment III is a double walled skirt 4I between the wallsof which are provided a plurality of pairs of tubular air ducts 42 and44 communicating with vapor chamber IIl and liquid chamber I2,respectively. For this purpose, the outer Wall of vaporizng chamber I issuitably apertured as at 46 and the outer wall of liquid chamber I2 issuitably apertured as at 48. It will be noted that the apertures 48 inthe wall of the liquid chamber preferably are disposed beneath thenormal level of the liquid therein whereby the air draft through theducts 44 will bubble through the liquid whereby to initiate somebreaking up of the liquid when it is drawn into the vaporizng chamber.

The outer ends of the tubular air ducts 42 and 44 open upwardly of theliquid chamber I2 and preferably terminate in a single plane whereby tobe more readily associated with a slide valve in the form of anapertured collar 50 manually rotatable by the projection 52 andsupported upon the skirt 4| by means of lugs 54 whereby reciprocal orrotary 'movement thereof may vary registration of the apertures with thefree ends of the various pairs of air ducts 42 and 44 to control theadmission of air thereto.

A closure 56 at the upper'end of housing A supports a tubular outlet Bfor the vaporous products issuing from vaporizng chamber I 0. As clearlyshown in Fig. 1, the tubular outlet 58 has a portion 50 thereoftelescopically arranged with respect to internal flue 32 whereby toprovide a reversely curved flow path for the exiting vapors as indicatedby the arrows in Fig. 1. This arrangement provides a Ibarile for theexiting vapors and also oil'sets or removes the vapor outlet from thevaporizing chamber III and associates the vapor outlet with the flue 32so that in the event of backiire or the like the pressure will bereleased through operation of safety valve 38 disposed at the oppositeend of flue 32 and will not carry into the vaporizng chamber I0. Athrottle or feed valve 62 to regulate withdrawal of vapors is disposedinternally of tubular outlet 58.

In the operation of the device above described, the outlet end thereof.may be suitably connected to the inlet manifold of an internalcombustion engine indicated generally at B in Fig. 4 or to the suctionside of a blower as indicated generally at C in Fig. 5 and the liquidinlet end thereof suitably connected to a fuel supply.

Slide `valve 50 may be`adiusted to the extent necessary to control theadmission of air to air ducts 42 and 44 communicating with vaporizngchamber I0 and liquid chamber I2, respectively, and in response to thesuction exerted by the intake manifold B or the blower C, predeterminedquantities of liquid and air will be drawn into the vaporizng chamberIl! and into the steel wool or other packing material I4 whereby theliquid will be broken up into a finely divided vaporous condition, thevaporous mixture thence passing to the outlet tube 58 and its withdrawalinto the manifold B or the blower C regulated by means of throttle valveB2. Valve 30 disposed in liquid inlet 20, being responsive to the liquidlevel in chamber I2, will function to maintain the liquid in chamber I2at any desired predetermined level preferably short of lower screen I6which supports the mass of steel wool or equivalent material I4. y

It will be apparent that if the filtering or dispersing material I4becomes contaminated or if for other reasons it is desirable to removethe same, closure 56 may be removed from the housing A, upper screen I6unseated and the mass I4 readily withdrawn and replaced or replenishedand the device again assembled by reverse steps. Provision of the steelwool or mass of equivalent material I4 makes it possible tol effect afine vaporization of relatively heavy fuels on the order of kerosene,fuel oil or the like, without the necessity of applying added heat toeffect or assist in effecting vaporization thereof. In this respect thedevice is simpler in construction and possesses fewer parts than priordevices and has been found to -be extremely. eiiicient in operation.
